Over-engineered play stack for infinidim.net — Stalwart wired into the shared Postgres + Redis + Garage S3 over the tailnet, with no WAN presence. Public mail ports are fronted by a separate caddy-l4 layer-4 proxy (caddy/) that can run on any tailnet host tagged tag:reverse-proxy — decoupled from the mailbox. - docker-compose.yml: ts-stalwart sidecar + stalwart, backends via MagicDNS - config/config.toml: PG (data/fts) + Redis (lookup) + S3 (blob) strawman - caddy/: xcaddy build with caddy-l4, JSON layer-4 mail proxy, own compose - acl-snippet.hujson: tag:stalwart owner + backend/edge grants - .env.example + gitignored .env (pulled from shared infra) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# Design: Stalwart runs as a Tailscale sidecar with NO WAN presence. A
|

# layer-4 (TCP) Caddy proxy on a public-IP host pipes the raw mail ports to it
|
||
# over the tailnet. The proxy can live on a DIFFERENT machine than the mailbox
|
||
# — that's the whole point. See CLAUDE.md.
